So this is your therapist's contempt for you that you are talking about? Has she told you she has contempt for you or is this your interpretation of her feelings?
If she is genuinely feeling contempt towards you she should be trying to work it out in supervision or personal therapy because it is likely that it would be about her own stuff rather than anything you have done. If she is not capable of that, and her feelings are getting in the way of therapy she would ethically have to refer you out because therapy isn't supposed to be about her feelings.
If, on the other hand, there's a chance you have misinterpreted her feelings, then it is a good idea to discuss it with her and try to work out what is happening between you. If you are seeing contempt where there is none, this is absolutely part of the work of therapy.
I have no idea which of those options is true, but I think it would be a good idea to keep an open mind and share your suspicions with her. If things really aren't working after you have tried to resolve it you always have the option of moving on.
